d- block elements are considered as transition elements except Zn , Cd , Hg. Here operatornameSc(Z=21), operatornameMn(Z=25), Mo (Z=42), Hf ( Z =72) are transition elements.

$d -$ block elements are considered as transition elements except $Z n, C d, H g$ .

Here $Sc (Z = 21), Mn (Z = 25),$ Mo $(Z = 42)$ ,

$H f (Z = 72)$ are transition elements.
